SOUND-EMITTING DEVICE.

Application filed January This invention relates to improvements insound emitting devices capable of pro ducing a crying sound upon beingmaneuvered to cause its internal elements to change their relativeposition.

One feature of the invention is in the provision of means whichautomatically modulates the sound produced, causing a difference inpitch between the earlier portion of sound and the final or mainportion.

A further purpose is to produce a device that is essentially simple andcheap to construct, instantly responsive to positional changes anddependent wholly upon gravity in the performance of its functions,

These and other allied aims and objects are accomplished by thearrangement of parts in the structure hereinafter described and shown inthe accompanying drawing, forming a material part ofthis disclosure, andin which Figure 1 is a top plan view of a sound emitting device, made inconformity with the invention.

Figure 2 is a longitudinal sectional view taken on line 2'2 of Fig. 1.

Figure 3 is a plan view of the device showing the cover portion removedand looking in a plane indicated by the line 33 of Fig. 2. i

As shown in the drawing, the mechanism is enclosed in a thin metalcasing 10, an elongated rectangle in shape, having a depression 11 and,near its raised upper edges is .an outstanding bead 12.

Resting on the head 12, when in position on the casing, is a cover13'having a raised rim 14, forming a depressed panel 15 containing aplurality of fancifully grouped perforations 16, larger openings 17being symmetrically disposed.

Fixed in the depression 11 is a flat block 18 secured by a screw 19,this block forming the base member of a bellows, the upper or movablemember 20 of which is secured by a hinge 2.1,, such as a flexible stripof leather attached to the adjacent ends of each mem ber. 7

The bellows further include a thin flexible element 22, such as leatheror textile fabric rendered air resistant, this material being cementedto the edges of the members 18 and 20 so that no air can leak.

At the end of the upper element 20, opposite the hinge, is a weight 23of such 24, 1925. Serial No. 4,419.

character asto normallyclose the bellows from an open position, as shownin the broken lines in Fig. 2, to the closed position shown in fulllines therein. 7

At about the center of the upper member 20 is an opening 24, over whichis a reed 25, fixed on a plate 25 its projecting ends being fixed to thetop of the member by any preferred means. An inverted metallic cup 26 isdisposed over the opening 24, covering the reed 25, but avoiding contactwith the same, the edge of the cup being held by an adhesive on theupper surface of the member 20.

The cup 26, has a relatively large perforation 27 at its center and atone side a minute vent perforation 28 permitting a limited passage ofair, these perforations constituting'major and minor openings.

Secured to the innersurface of the end wall of the cover13, adjacentthehinge, is the flanged foot 29 of a resilient leaf 30, ex-

tending normally straight and parallel withwhen the bellows is expanded,as in the broken lines inFig. 2, covering the opening and preventing thepassage of air during theearlier part of, the bellows movement whenclosing, air at that time passing through the perforation 28. I

In operation the device is raised and inverted from the position shownin Fig. 2, the weight 23 causing the bellows to expand, air beingadmitted to its interior through the openings 27 and 38, the formerbeing closed during the latter part of the opening by the leaf element30.

Upon reversing the device, into the position shown, air is forced out ofthe bellows by reason of the weight, the air passing to vibrate andproduce sound of a certain intensity or tonality, the air escaping intothe cover through the small perforation 28; later, when the largeropening 27 is released from the spring leaf, 30, the bellows closes morerapidly and the volume of sound is through the opening 24, causing thereed 25' i increased and changed, producing a difi'erent I note, thesounds eventually escaping into the atmosphere through the openings inthe cover.

Thus it will be seen that the cover carried flexible leaf 30 operatesautomatically to modulate the sound-produced and also to accelerate theinitial closing of the bellows.

Although the foregoing is descriptive of the preferred embodiment of theinvention, it will be apparent that minor changes may be made in itsconstruction, without the exercise of invention or conflicting with thepressi'on, the movable element; of said bellows being hinged at one endand having a central opening and carrying a weight, a reed disposed inthe opening, an inverted cup fixed on said movable element to cover saidreed and opening, said cup having a major and minor perforation, and aflat resilient member carried by said cover at the end of said casingadjacent the bellows hinge adapted to close the major perforationtherein when the hinged portion of the bellows is partially raised.

2. A sonnd'emitti'ng device comprising a rectangular casing having acentrally depressed port-ion, a perforate cover tight fitting thecasing, a bellows fixed in the depressed portion of the casing, saidbellows having a hinged element containing an opening. a weight on saidhinged element, a vocal sound producer including a reed fixed on saidelement over the opening, a cup cnclosing the Vocal element and having acentral relatively large opening and a small opening,

and means carriedby said cover to close the central opening at theinitial stage of bellows closure.

3. A sound emitting device comprising an oblong rectangular casing, acover reinovably engaged. on said casing, a stop on said casing to limitthe cover, a bellows in the casing, said bellows being gravity operatedupon reversion, a reed vibrated by air from the bellows, an inverted cuppermanently secured on said bellows to cover the reed, said cuphavin'g'an air passage, and a spring leaf carried wholly by said cover to modifythe transit of air through the passage during the initial exhalation ofair from said bellows, said leaf being" in contact with the movable partof said bellows when open to cover the passage therein.

4. A sound emitting device comprising a casing having a cover, a bellowsin the easing, there being an opening in the movable member thereof; areed vibrated by air from the bellows disposed adj acently over theopening, a convex cover over the reed and opening, said convex coverhaving two perforations of unlike area; and a flat spring leaf having apart secured to said cover and another part adapted to restrict thepassage of air from the'bell'ows through the larger of the mentionedopeningswhen the bellows is fully expanded and during the earlier partof its closing movement, all of said elements being enclosed within thecasing.
